ZyWAN-G9 - User Manual
94 110150-4002A
The following screen capture shows the Table of Terminal Servers .
Note:
Any Terminal Server (TCP) ports configured here must also be included in the Open Ports
section of the Networking page, so the firewall will allow connections to be made to the
ZyWAN-G9.
The following table lists the fields and options that are available and that must be set for each
configured
Terminal Server configuration.
FIELD/OPTION
EXPLANATION
IP Port
Enter the IP port number (between 1 and 65535) to be used on the ZyWAN-
G9 for incoming TCP/IP connections from a network client application. The
IP address to which the client connects may be any valid address
configured for the ZyWAN-G9 on any interface.
Time to Live Enter the Time To Live for the connection (in seconds). This is the
maximum time of no activity from the network-connected client, before the
ZyWAN-G9 closes the Terminal Server connection. The range for
Time To
Live is 1 to 65535 seconds. (Setting the value to zero (0) will cause the
Terminal Server to never shut down upon no activity, which is not
recommended.)
Duplex Select the duplex mode for the Terminal Server. This selects a mode of
operation for handling bi-directional communication with a serial device.
Full Duplex : This mode is designed for unsolicited data from serial devices,
full bi-directional communication, or any serial protocol which may send
large or multiple responses to a request. In this mode, the Terminal Server
is always able to receive data on both the serial and network ports, as long
as a client is connected to the
IP Port .
Half Duplex : This mode is designed for simple request-response networks,
especially where serial port sharing with another Terminal Server may be
required. After a request is received from the network and sent to the serial
port, one response is expected (with a number of bytes less than the
Buffer
Size ). After data is transmitted to the serial port and the Response Timer
times out with no data or after one response is received and returned to the
network client, the Terminal Server does not read any more serial data until
the next request.
